Is it possible to build charts like this? about swiftcharts HOT 6 CLOSED

Yes. You will find everything you need in the examples, just have to combine the different components appropriately. The legends on top are not provided. You have to implement those views yourself.

Thanks for your response, how can I get the vertical lines crossing through the circle points in the above chart and for the second chart candlestick will work I believe.

You can use ChartPointsViewsLayer where you can pass a view generator which creates an UIView for each point... so basically you would have a layer that creates the line views, and another on top that creates the circle views (and of course layers for guidelines, axes, the dotted overlay etc.). You would use this for both charts. Here https://github.com/i-schuetz/SwiftCharts/blob/master/Examples/Examples/BarsExample.swift#L40 you see ChartPointsViewsLayer used to generate bars. Or also here https://github.com/i-schuetz/SwiftCharts/blob/master/Examples/Examples/HelloWorld.swift#L43 there's a layer that generates a UILabel for each chart point.

Edit: To determine the top and bottom screen locations of the lines there are methods in ChartPointsLayer, which is passed to the view generator - like modelLocToScreenLoc which calculates screen location for model coordinates. In one of the candlestick examples - https://github.com/i-schuetz/SwiftCharts/blob/master/Examples/Examples/CandleStickInteractiveExample.swift#L100 you can see this in use.

You also can use a layer for the highlighted area between 80 and 140 in the first chart. The quickest approach would be to use also a ChartPointsViewsLayer, pass a dummy chart point to it and generate a view that covers this area. To calculate the frame of this view you would also use modelLocToScreenLoc.

Thanks. :)

How can I get the X-axis values in 12 Hr. format 12 AM, 12 PM, 12AM and as shown above how to customise for the week(Today and 21 Nov). I'm using ChartAxisValueDate for creating week and month but having trouble customising it.

from swiftcharts.

You can implement your own axis values, by subclassing ChartAxisValue. There you write custom logic to map between model data / internal value (scalar) and labels.
